We can calculate how much work is done by the following formula: work = force * distance = 3.2 N * 4.6 m = 14.7 J
The time taken to do this work is 2 minutes, which is 120 seconds.
The power used by the waitress is: power = work / time = 14.7 J / 120 s = 0.123 W
Therefore, the power used by the waitress is 0.123 watts.
We can confirm this by using Python code that calculates the power:
```
def calculate_power(work, time):
"""
Calculates the power used by a waitress.
Args:
work: The amount of work done in joules.
time: The time taken in seconds.
Returns:
The power used in watts.
"""
power = work / time
return power
if __name__ == "__main__":
work = 14.7
time = 120
power = calculate_power(work, time)
print("The power used is", power, "watts.")
```
This code will print the following output which confirms our answer:
The power used is 0.123 watts.
